Figure 5. Graph of intratumoral and rectal temperature courses during exposure of 10 tumor-bearing mice to an alternating magnetic field (frequency, 400 kHz; amplitude, 6.5 kA/m) for 242 seconds after intratumoral injection of 21 mg ± 9 of magnetite (sample 6) per 299 mm3 of tissue. The intratumoral temperature, which began at 26°C ± 1, increased to 71°C ± 8 at the end of treatment (242 seconds). No substantial increase in rectal temperature was observed.
